Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed December 19. 1906. Serial No. 348,600.

To all whom 'it may concern.'

Be it known that HENRY Mone-AN lion- INsoN, a citizen of the United States, residing at the city of Nashingtoin in the District of Columbia, have invented new and useful improvements in Toys, of which the following is a specification.

The invention relates generally to an improvement in toys, and particularly to a toy constructed and arranged to simulate in structure and operation a grinding mill'.

The main object o'f the present invention is the production of a toy simulating in appearance and operation a grinding mill adapted for the reduction of grain, the construction including the successive series of compartments .in which the grain Vis to be treated in the transition from the kernel to the -linal product, earn of said compartments being closed against the remaining compartments, and eacn adapted to contain a quantity of material in the condition usual to such compartment in `the actual grinding operation, such operating means being arranged in eacn compartment as will so affect the material therein as to indicate to the observer tue actual transfer of the material from one compartment to another.

The preferred embodiment of the details of construction of tue present invention will be specifically described in the 'following specitication, reference being nad particularly to the accompanying drawings, in which:-d

Figure 1 is a view in side elevation, partly in section, illustrating the construction of the improved toy, F 2 is an end elevation of the same, Fig. 3 is a plan view of the same, Fig. l is a broken vertical section on the line 4 4 of Fig. 3, Fig. 5 is an enlarged vertical section, partly broken olf on t'ne line .5#5 of Fig. 2, Fig. 6 is a broken vertical section on the line 6 6 of Fig. 1.

Referring particularly to the drawings, wherein similar reference numerals indicate like parts throughout the several views, my improved toy grinding mill comprises a reetangular box-like structure 1, hereinafter termed the 'feeding compartment, and designed to receive tne grain in the original or kernel form. Tue feeding compartment, except as hereinafter noted, is open at the top, and is in communication adjacent its bottom with n elevator casing 2, the medium of communication being in the form of a pipe connection 3.

or preferred construction, the form shown including spaced rectangular side sections 3, in communication with and connected to the upper and lower end sections 4 and 5. In the respective end sections are mounted carrier wheels or rollers over which travels an endless carrier belt 7, provided at determinate spaced intervals with buckets 8.

The relatively forward portion of the feeding compartment is closed by a cover section t), connected to and supported by the end walls of the compairtment, said cover section extmuliug forwardly beyond the relatively forward wall of the feeding compartment. The rear end of the cover section, or that end overlying the feeding comparlunent is provided 'with a depending section 10 extending at right angles to the cover section and terminating at its lower end within the compartment below the upper edges of the front and rear walls thereof. The cover scctiont) extends forwardly beyond the relatively forward wall ef the feeding compartment, as at 11, to provide a platform section, said plat form being of materially less width than the normal width of the cover section and projecting from said section at the end thereof next the elevator 2.

',lho lic-ad section 4 of the elevator is in operative cennnunication with a delivery spout 12, so arranged relative to the head section that the material elevated in the buckets S will be delivered to the spout. Beyond the elevator casing the spout 12 is dellected laterally to arrange its mouth centrally over and above the platform 1l, and on said platform, supported by a framework 13, is arranged a hopper 1li underlying the mouth of the delivery spout 12 and adapted to receive the material therefrom. rl`he hopper bottoni is formed with an opening 15, through which the passage of the material is controlled by a manually operable valve plate 16, the material passing through the opening 15 being delivered through an opening 17 in the plate form 11 by a tube conveyor-18.

lhe side edges of the platform 11 are connected by walls 20, forming with said platform a box-like structure, thc walls 2l) extending somo distance in advance of thc forward edge of the platform and terminating at their lower edge in alinement with the bottom of the feeding compartment to provide a supporting base for the structure.

Between the walls 20 and below the plat` '.lhe elevator casing 2 may be of any usual form 11 is secured an approximately circular wall 21 within which is included the initial grinding compartment 22. At the relatively rear portion the wall 21 coincides with the upper edge of the forward wall of the feeding compartment, the upper portion of said wall 2l being spaced from the platform 1 l, whereby to provide an entirely inclosed chamber 23 arranged between theplatform and the wall 23, which chamber is closed at its forward end by a section 24 depending from the forward end of the platform and connected at the lower end to the wall 21. The compartment 23, as thus arranged opens directly into the feeding'compartment, to permit the passage lof material through the opening 17 in the platform to the feeding compartment, the rearward and downward curvature of the wall 21 serving to direct the material into the feeding compartment by gravity.

The upper section of the wall 2]. is projected forwardly and downwardly in advance of the depending section24 to provide a ledge 25, the lower section of the wall 21 being spaced from the terminal of the ledge 25'and projected in advance of said ledge in the form of an upwardly and forwardly curved section 26. The side walls 2() have their upper terminal edges at this point extended forwardly from the free edge of the ledge 25, thereby providing side walls 27 connected at their forward ends by an inclined wall 28, forming with the bottom 26 a hopper 29, fully open at the top. Supported by the side walls 20 and arranged between the upper and lower projected portions of the wall 21 is a partition plate 30, slightly curved in vertical section and having its upper and lower edges spaced respectively from the inner surfaces of the upper and lower projected portions of the wall 21. The partition is practically concealed by the ledge 25, and by its position provides upper and lower channels 31 and 32 through which the compartment 22 is in communication with the hopper 29. Within the compartment 22 is mounted a revoluble carrier 33, comprising a drum or roller upon the periphery of which is arranged a series of cups 34. The cups are so disposed and of such form that in the operation of the carrier they will elevate the material in gthe lower portion of the compartment 22 to the upper portion thereof, operating to so discharge the material in the upper portion of the compartment that it will be directed through the channel 31 into the hopper.

VIn advance of the initial grinding compartment 22 is arranged a second circular wall 35, practically identical with the wall 22 and serving to inclose a final grinding compartment 36. The rear portion of the wall 35 is arranged beneath the hopper 29, a portion of the wall 35 preferably coinciding with the bottom 26 of the hopper. Beyond the hopper the wall 35 is extended to form a ledge 37, the lower portion of the wall being projected forwardly and upwardly beyond the forward edge of the ledge, as at 38. irlhe side walls 20 at this point terminate coincidently with the forward edge of the ledge 37, and are connected at the end of the wall 3S with an inclined wall 39, forming with the side walls 20 and the bottom 38 a hopper 40. Beneath the ledge 37 is arranged a partition plate 41, spaced at its upper and lower `edges from the projected portions of the wall 35, thereby providing upper and lower channels 42 and 43 to establish communication between the hopper 40 and the compartment 36. YWithin the compartment 36 is revolubly mounted 'a carrier 44, similar to the carrier 33, -and peripherally provided with a series of cups 45 adapted in operation of the carrier to elevate material from the lower portion of the compartment 36 to and discharge the same through the upper channel 42 into the hopper 40.

Laterally of the hopper 4() is arranged a second elevator casing 46, practically identical with the casing 2, and including spaced. side sections 47, and upper and lower end sections 48 and 49. `Within the end sections are mounted rollers 50 over which travels an endless belt 51 carrying buckets 52, whereby material accumulating in the lower end section 49 may be elevated and delivered to the upper end section 48.

A conveyer 53 is arranged between the adjacent side wall 20 and the proximate wall of the elevator casing, said conveyer being supported on the base plane of the structure, and, therefore, to one side of the hopper 40 and approximately in alinement therewith transverse the structure, as will be clear.

from Fig. 3. rf'he conveyer comprises side walls 54 connected at their respective ends with the wall 20 and with the elevator casing wall. Immediately adjacent the w all 2() the relatively forward half of the bottom 55 of the conveyer is curved in a forwardly and upwardly direction, as at 56, the section of the bottom in rear of the curved portion supporting a box-like casing 57, the rear wall 4of which engages the rearwardly disposed side wall 54 of the conveyer, asshown. The forward wall 53 ofthe casing is formed with a discharge port 59 in its relatively upper portion and with an inlet opening 60. Within thc casing` is arranged for revoluble movement a cylinder 61, peripherally provided with approximately spiral blades 62, the function of which is in the revolution of the cylinder to elevate the material from the lower portion of the casing 57 and discharge the same through the outlet 59 onto the curved bottom 56. l

Supported by and in advance of the forward wall of the elevator casing 46, at the extreme upper portion of the head section 48,

is arranged a cylindrical body 63, preferably of hollow construction and hereinafter termed the bolter. Supported upon the upper wall of the elevator casing is arranged a box-like casing 64 divided by transverse vertically disposed partitions 65 and 66. Between the partitions 65 and 66 within the casing 64 is mounted for revoiuble movement a cylindrical body 67 having peripheral wings or blades 68. tition 66 is provided near the relatively upper edge with a discharge spout 6) and at the lower edge with an inlet opening 70. 'l`he relatively rear wall of the bolter, as 7l, projects forwardly from the upper wall of the elevator casing, being upwardly cmved as shown, the forward edge of said wall meeting the relatively upper portion of the w ail of the bolter at a point in advance of the forward edge ofthe casing o4. A eliamber 72 is thus provided between the forward end of fne discharge spout 6) and the relatively rear wall of the bolter, which chamber communical es through the discharge spout 6) and opening 7() with the chamber between the partitions 65 and 66 in which is mounted rthe c vlinder 67.

The elevator casing 46 communicates at the upper end with a discharge trough 7 3, so arranged that the material elevated by the buckets 52 is discharged into said trough. At the lower end the trough communicates directly with the upper ends of two discharge spouts 74 and 75, being at the point of communieation provided with a .manually operable gate 76, by which the material may be deflected into either discharge spout, as will be apparent from Fig. 6. The lower end of the discharge spout 7a communicates with a storage compartment or bin 77, approximately identical in size and shape with the feeding compartment 1. rlhe upper portion of the storage bin is partiallyr closed by a cover section 7S, the remaining portion being open to the inspection of the operator. The bin 77 is connected directly to the elevator casing 46, a portion of the rear wall of the bin forming the forward wall of the casing. In this wall at the lower end isformed an opening 79, providing a communication between the bin and the lower end section eff) of the elevator casing, said opening being preferably controlled through a manually operable valve plate S0 slidably mounted in the cover section of the bin.

The shafts on which are mounted the rollers 6 and 50 in the relatively upper ends of the respective elevator casings, are projected beyond the side walls of said casings and provided with belt rollers Sl, the shaft of the carrier 33 being similarly projected and provided with a series of three belt rollers S2, S3 and 84. A belt S5 operatively connects the belt rollers Sl of each elevator casing and the i belt roller S2 of the carrier 33, the belt roller 83 of said carrier being arranged to receive a The forward par- I belt (not shown.) from any suitable source of power, as a toy engine or the like. The shafts of the respective carriers 33 and f4 are also projected beyond one of the side walls 20 and provided with belt rollers 86 operatively connected by a belt S7, whereby to transmit power to said carriers. The side wall 2() immediately above the conveyer 53 is provided with an idler shaft on which is mounted a belt pulley connected by a belt 89 with the belt roller Sel, the outer face of the pulley SS being provided with a bevel pinion 90 arranged to mesh with and drive a bevel pinion 91 mounted on the upper end of the shaft 92 of the cylinder 61 in said coi'iveyer. The inner `face of the belt pulley 81 fixed on the shaft of the elevator roller 5() is formed with a bevel pinion engaging a bevel pinion 93 on the end of a shaft tiff mounted on the side wall of the elevator casing, the upper end of said shaft having a bevel pinion 95 adapted to operate a second. shaft J6 also mounted on the side wall of the casing through the medium of an interposed bevel pinion 97. The upper end of the shaft 96 is formed with a bevel pinion 9S arranged in mesh with a bevel pinion 9S) formed on the lower end of" the shaft 100 of the cylinder 67 in the casing (S-f.

as thus constructed it will be noted that the improved toy closely simulates a grinding mill, and includes a feeding compartment, an initial grinding con'ipartment, a final grinding compartment, and a storage or delivery bin; that each of these compartments are entirely free of communication with cach other; and. that each compartment is so arranged as to indicate to the observe;

the delivery of material from one compartment to the next succeeding compartment.

,in 'the use of the toy the material in the original or kernel form is placed in sufficient quantity in the feeding compartment l.. The hopper 27 and the initial grinding compartment 22 is supplied with material in 'the form ordinarily incident to the initial grinding operation of an actual mill, that is, in a partially reduced condition. The hopper 4() and the conmartment 3G is supplied with material in the condition incident to the final grinding operation of an actual mill, that is in a finally reduced condition. Material in this finally reduced condition is also deliverefl in desirable quantity to the eonveyer 52%, the bolter chamber 72, and material incident to the bolting operation is delivered indesirable quantity to the storage bin 77. ln 'this condition the mill is ready for operation. VUnder power the various vmovable parts described are operated, with the effect that the buckets S in the elevator casing 2 will pick up the material from the feeding comparlunent and deliver the. same to the hopper l-t, whence said material finds ifs way into the chamber 23 and thence directly into the feeding compartment. As the discharge' passage 'from the hopper, however', is located directly above the initial grinding compartment it appears to the observer that the material is delivered Vfrom the hopper let directly into the initial grinding compartment 122. The partially reduced material in this initial grinding compartment, is, through the operation of the cai ier 33 continually withdrawn from and delivered to the hopper 29 through the channels 3l aml 32, but as said hopper is located directly above the linal grinding compartment 36, the material in the hopper 29 is, apparently, delivered directly to the final grinding compartment. The material in the final grinding compartment is similarly Withdrawn from and returned to the hopper 40, tl'iough in appearance, owing to the disposition of the hopper directly above the conveyer 53, said material is apparently delivered from the hopper directly to the conveyer. As the result ol the agitation of the blade 62 on the cylinder 6l in the conveyer the material therein, through the medium of the inclined bottom 56 is continually drawn into the opening 6() and discharged through the opening 59, thereby agitating the material in the conveyer and apparently forcing the material from the conveyer into the elevator casing 46. The material in the chamber 7 2- is similarly agitated through movement of' the cylinder 67, With the e'liect to simulate the delivery ol the material from the elevator to the bolter, While as a matter of fact, said material is being delivered. through the discharge spout 74.

'into the storage bin, the material accumulating'in the latter serving through the opening 79 to recharge the lower end section of the elevator casing and continually serves the elevator buckets.

rl`he effect of the operation described to the observer is that the material is delivered from the hopper to the initial grinding chamber, thence to the final grinding chamber, thence through the conveyer to thc elevator casing 46, thence to the bolter G3, and linally through the discharge spout to the storage bin.

By proper operation of the gate 76, the material may be directed through. the discharge spout 75, the terminal of which is disposed beyond the plane ol the storage bin. The spout .75 is to be used when bags or other receptacles are to be lilled with material, as might be desirable in some uses ol" the toy.

rlhe toy as a Whole is to be constructed in any size, or of any material, being` preferably, however, made up of sheet metal which may be covered or ornainented to represent an actual grinding mill structure. A substantial base may be provided. il desired, While preferring that the mill be driven by power, it is equally obvious that hand operation will produce the same results.

einem The construction described illustrates the preferred embodiment oi' the details of this invention, but it is to be distinctly understood that l contemplate as Within the spirit olthe present invention such variations and i changes in the structural details, as may properly lall Within the sccpe of the appended claims.
